This is an interesting and helpful overview of political theology for those interested, esp. for anyone interested in how Political Theology works within the context of wider theological thinking. However, it is somewhat disengenuous for Continuum (the publisher) to claim that this is a 'Guide for the Perplexed', it is much more a guide for those who already have a good understanding of both political theory and theology. The first few chapters are useful for those who want a basic overview of the basic types of political issues, and the issues therein (I found the sections on Augustine, Luther and O'Donnovan partilarly helpful). However, it quickly got bogged down into ethical and theological-political theory which left me more rather than less perplexed. (I suspect that it might be better read a taught course in political theology, allowing the lecturer to elucidate some of the more obtuse parts of this area.
It would also have been helpful if the author had explored key Biblical texts more, such as Romans 13: 1-7 and sections of Revelation, texts which are key to how the Church (and theologians) then (and now) has understood the nature and role of the State within the context of the Kingdom of God. These are texts that have been open to debate and different thinkers, e.g. Augustine, Luther, Barth, Yoder and Hauerwas have each had different ways of interpreting and understanding these texts, always read from within thei rown political and social context and each have helped influence and shape the way in which these texts are read in their own time (and our own). Our own understanding of Romans 13 has changed since Augustine/ Luther, particularly with the understanding that the State is not an a-moral actor or even an actor working for the good of its subjects, but often as (as the Holocaust proved) an immoral actor.
